Need suggestion on single supply rail to rail op-amp to use with arduino uno?

Using Arduino General Electronics
5
  1. By using TLV2371, I can bias at 2.5V and use from Gnd to +5V, right?
  2. Whats the maximum gain of TLV2371? I need maximum gain of 200 either with single op-amp (like lm386) or dual op amp (like lm 358)?

Thanks
